Welcome to Wyldor, where the military controls the city gates and no one gets in or out without their permission. When Jade Ember, a street thief, accidentally kills a soldier, she is forced into hiding. If she cannot find a way to escape the city, then she will pay for her crime with her life. Her only hope is to turn to the Brohavee, rebels depicted by the Wyldorian General as bloodthirsty savages. Jade soon discovers the Brohavee aim to stop the General and his notorious Coremaker from raising an army of mechanical giants fueled by human souls. The rebels are all that stand between the General and his domination of the Northern Territories.
